FULL PRODUCT VERSION :
Information:javac 1.8.0_40 was used to compile java sources

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows [Version 6.1.7601]

A DESCRIPTION OF THE PROBLEM :
I am compiling a piece of code with various errors, but besides normal error messages about the errors in my code, I also receive an internal compiler error.

I receive the following messages about errors in my code as expected (line numbers are off due to editing)

Error:(16, 17) java: method x in class saganaki.t0006_internet.X cannot be applied to given types;
  required: no arguments
  found: (t)->new X()::run
  reason: actual and formal argument lists differ in length
Error:(16, 25) java: invalid method reference
  cannot find symbol
    symbol: method run()
    location: class saganaki.t0006_internet.X

but before those errors I receive this:

Error:java: java.lang.ClassCastException: com.sun.tools.javac.code.Symtab$4 cannot be cast to javax.lang.model.element.TypeElement


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
paste the code snippet given below in a source file and compile. (Actually, I am using IntelliJ IDEA, but it says "Information:javac 1.8.0_40 was used to compile java sources", so I assume it will also happen if I just use javac by myself. But testing that would require, ugh, command line. ew.)

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
I should have received only errors about mistakes in my code.
ACTUAL -
Besides the errors in my code, there was a compiler error.

ERROR MESSAGES/STACK TRACES THAT OCCUR :
Error:java: java.lang.ClassCastException: com.sun.tools.javac.code.Symtab$4 cannot be cast to javax.lang.model.element.TypeElement

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
final class X
{
X()
{
}

static void x()
{
x( t -> new X()::run );
}
}

---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
The internal compiler error does not occur if I give it valid java to crunch.
